The Northwest Power and Conservation Council (NWPCC) is the official power planning agency for the states of Idaho, Montana, Oregon and Washington. The Council is directed by the Northwest Power Act of 1980 to prepare a program that protects, mitigates and enhances fish and wildlife of the Columbia River Basin affected by hydropower dams, while also assuring the region an adequate, efficient, economical and reliable power supply. The Council is funded by wholesale power revenues from the Bonneville Power Administration. Every five years, the NWPCC conducts a fresh assessment of the region’s long-term electricity needs and issues a Power Plan for meeting them. Bonneville Power Administration and the Northwest’s electric utilities use these plans to guide their resource choices for affordably meeting customer needs. NWPCC’s Sixth Power Plan covers the period from 2010 through 2029.
